It queries a local DNS server 172.16.1.31 based on BIND9. #dig microsoft.com ; <<>> DiG 9.3.3rc2 <<>> microsoft.com ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 54880 ;; flags: qr rd ra; QUERY: 1, ANSWER: 2, AUTHORITY: 5, ADDITIONAL: 5 ;; QUESTION SECTION: ;microsoft.com.
